Today, Cartoon Network kicked off its fifth annual Stop Bullying: Speak Up campaign with a video call-to-action encouraging people to speak up on behalf of kids via social media using #ISpeakUp. The goal is one million user-generated videos that unite the voices of kids, parents, educators, celebrities and government officials, each committing to speak up—either themselves or to a trusted adult—when someone is bullied. Select videos from participants will become part of new campaign spots to appear on Cartoon Network, its digital platforms and Boomerang throughout October.

"We're so proud of the youth who inspired this campaign by their courage and kindness. Our goal is to give young people, and the adults who care for them, the confidence and competence to speak up safely and effectively when bullying happens," said Alice Cahn, Cartoon Network's Vice President of Social Responsibility, in a press release. "Working with expert partners nationwide, Cartoon Network provides practical bullying prevention advice kids can put into action. This new phase of our campaign is meant to empower anyone who wants to take an active role in seeing bullying come to an end. We embrace and thank the one million people out there willing to publicly take a stand; coming together, we can all make a difference for our nation's children."

The initiative, which first launched in 2010, will culminate during Cartoon Network's Speak Up Week September 29 through October 3, as a kick-off to National Bullying Prevention Month in October. During this week, in addition to the videos, Cartoon Network will air shorts, bumps and PSAs with anti-bullying themes featuring the overlying message that "speaking up" should become the action when bullying occurs. Each message will remind viewers to visit StopBullyingSpeakUp.com to learn how they can participate in the one million video challenge. Additional spots will feature animated characters from Cartoon Network's original series interacting with kids and families who have shared their "I Speak Up" message at StopBullyingSpeakUp.com. Furthermore, Cartoon Network, Boomerang and Turner Broadcasting sister networks TBS, TNT, CNN, HLN, NBA TV and truTV will air special bumps showcasing recorded messages from Turner celebrities encouraging even more viewer participation. Finally, an official "I Speak Up" tally will appear onscreen each day noting how many people have officially "spoken up" by submitting videos and/or pledges during within the campaign.
